WINDOW -BLIN DS, DOORS, &C.

Specification of Letters Patent No. 13,141, dated June 26, 1855.

To all 'whom t may concern:

Be it known that we, LAFAYETTE STEVENS and SOLOMON B. ELLrrHoRr, ofElmira, in the county of Chemung, in the State of New York, haveinvented certain new and useful Improvements in Window-Blinds, Doors,&c., to be known as the Climax Window-Blind; and we do hereby declarethat the following is a full and exact description thereof, referencebeing had to the accompanying drawings and to the letters of referencemarked thereon.

Figure l, is a side elevation with the stile detached. Fig. 2, is anedge elevation with the stile detached. Fig. 3, is a detached side viewof a slat with t-he lever attached. Fig. 4, is the stile detached withthe groove to contain the strips and levers on the tenons of the slots.

To enable others skilled in the art to make, and use our invention wewill proceed to describe its construction and operation.

Fig. l, letter A is the frame; a, the slats; the fillet; c, the rodattached to the fork or lever; al, the lever with the ferrule drivendown on the tenon.

Fig. 2, e, e the rods for connecting the slats and operating themtogether; f, the ends of the tenons over which are driven the ferrulesof the levers Z in Fig. l.

Fig. 3, letter g t-he slat; L, the lever with the ferrule; h2, the leverwith the shaft.

Fig. 4, letter z' the stile; J, the groove in the same.

We construct our blinds in any of the known forms, or sizes, but we donot use the perpendicular rod that is attached by wires to each slat asnow in use, but we do away with that rod altogether for the purpose ofopening, and closing, the slats, thereby making a more beautiful panel,and one much more easily cleaned, and painted, as well as a saving inthe manufacturing of them.

The construction of our stiles, cross pieces, and slats, is the same asany of the old ways for doing so, except in one of our stiles, thisstile we make .lf of an inch narrower than the other one, and which isplowed or grooved out, of sutlicient depth, and width, to receive theapparatus for opening, and closing the slats, which we thus describe; weget out a fillet, or side strip of an inch in thickness, and as wide asthe stile is thick, the entire length of the panel we wish to make,which we bore to correspond with the holes in the other side, or stile,and through which we pass the tenons of the slats, we then put the blindtogether except the stile. When thus put together the tenons of the slatpass through the fillet far enough to receive the levers d, d, which areapplied as follows.

The levers are constructed thus. The lever is a fork with a flat shaft,or a fork with a ferrule as seen in Fig. 3. Letters il., h2 is the leverwith a shaft instead of a ferrule; if we use lever z we drive theferrule do-wn on the tenons, if we use lever h2 we drive the sha-ftint-o the end of the tenon ofeach slat, leaving the two prongs of thefork sticking up alike in both cases, and which is the same. Ve now taketwo rods one for each side of the lever, or fork, on the tenons, whichmay be made of metal, wood, leather or their equivalent, through whichwe punch, drill, or bore a hole to receive the prong or forked levers,at distances coresponding to the distances the slats are apart; we thenattach one of the rods e, e on each side of 'the fork or levers,' theprongs entering the holes in the rods, we then put on the grooved stilez' in its proper place so that the groove in the stile will receive therods, and forks, and by driving the stile down to the fillet, thelevers, that is the rods and forks) are all inclosed. The llet is thenfastened to the stile by brads or screws, and finish the Ablinds asusual, thus we have a beautiful blind that can be closed, and openedwithout having the rod in the center, and by merely turning one of theslats, they will all open, and close as may be desired.

vHaving thus fully described the construction and operation of ourinvention: what we claim as new and desire to secure by Letters Patent,is:

1. Ve claim the forked lever with the ferrule on the end; or the forkwith a flat shaft at the end, made of either cast or wroughtA metal forthe purpose herein set forth.

2. We claim the application ofthe rods e, e, made either of metal, wood,leather, or their equivalents as described, and for the purpose hereinset forth.

3. le claim the grooved stile with the fillet attached for the purposeherein set forth and described.
